O. Z.

O. Z. stands for being overzealous, a brain disorder.

Z. out of control.

Khren-o-tyen

Derived from the Russian colloquial word, хренотень (Khrenotyen), Khren-o-tyen literally means "shade of shit/junk". It is a term used to describe a sort of unknown or worthless stuff in a vulgar manner.
